The Walt Disney World Resort's third theme park officially re-opened as Disney's Hollywood Studios today. While the name change of the park formerly-known-as Disney-MGM Studios is now official, there is still much work to do to replace all of the former marquees and signs. As of the official change-over, the park has only added a new park entrance marquee and changed the name on park guide maps, event guides and some park information signs. Park exclusive merchandise reflecting the new name is expected to be rolled-out soon, but as of the change-over was not available. It is anticipated that all references to the former name will take several months to remove or replace.
